MINEOLA, N.Y. (CBSNewYork/AP) — The Nassau County District Attorney’s Office has ordered the retesting of ballistics evidence in about 45 criminal cases after the discovery of an error in lab work for a pending case.

Shams Tarek, a spokesman for District Attorney Kathleen Rice, said police found a mistake in lab work completed by one lab technician from an out-of-state facility.

The mistake was not used against anyone in the case, according to Tarek.

He said “in an overabundance of caution” evidence retesting was ordered for all other cases that the technician had worked on.

Tarek said 32 cases were open and there were 14 cases in which the defendant was already sentenced.
